Ball bearing slewing rings

Ball bearings are particularly suitable for applications exerting low to medium loads on the bearings. Usually, polymer spacers are installed between the rolling elements, although bearing designs with steel or brass cages are also available.

Technical information

Types of ball bearing slewing rings

Single-row four-point bearings are used, for example, for the slewing of excavators, the boom movement of tower cranes and as drive elements for large rope winches.

Single-row four-point bearings

Single-row four-point bearings are used, for example, for the slewing of excavators, the boom movement of tower cranes and as drive elements for large rope winches.

Special forms of seals are always used whenever bearings are exposed to particularly harsh environmental conditions, and protect the slewing bearing, for example, from seawater penetration.

Single-row four-point bearings with special seals

Special forms of seals are always used whenever bearings are exposed to particularly harsh environmental conditions, and protect the slewing bearing, for example, from seawater penetration.

Double-row four-point bearings can support significantly higher loads than single-row four-point bearings, for an equivalent diameter. They are used in applications with high loads and restricted installation space, such as for rotor blade adjustments on wind turbines.

Double-row ball bearing slewing rings are distinguished by their high cost-effectiveness and their robust design. They are used, for example, in crane technology.
